Abstract :
Two fully-differential track-and-hold and quasi-sample-and-hold circuits are based on AlGaAs/GaAs-HEMTs with 6OGHz f/sub T/. The less complex of these circuits exhibits 7b linearity measured under worst case. The ICs work up to 5GSample/s at a differential input of 2V/sub p-p/ for the track-and-hold and 3GSample/s for the quasi-sample-and-hold. The THA can be directly merged with the source follower input stage of an A/D converter and is also suitable for Si bipolar technology.
